Final answer:
The sievert (Sv) is the most common unit of measure of equivalent dose used to assess radiation damage, factoring in the energy of the radiation and its biological impact.
Step-by-step explanation:
The most common unit of measure of equivalent dose, which takes into account both the energy and the biological effects of the type of radiation, is the sievert (Sv). Units like gray (Gy), becquerel (Bq), and curie (Ci) are also used in the context of radiation, but serve different measurement purposes. The Gray is the SI unit for measuring radiation dose in terms of energy absorbed per kilogram of tissue, while the becquerel and curie are units for measuring the rate of radioactive decay. However, for measuring tissue damage, the sievert is used as it includes not just the dose but also the relative biological effectiveness (RBE) of the radiation.
